Re: Get Hash Value with two methods.But the one works finely, the other one is Exception.

You confuse something is this mail, because it's tmpmodename().key
that should work, tmpmodename().["$key"] that shouldn't work.
Supposing this was the case, there are two problems with the last.
First of all, the dot shouldn't be there; that's already a syntax
error. Secondly, although it's not an error, writing ["$key"] is
awkward, you could just write [key].
